Breast cancer type 1 (BRCA1) is a human tumor suppressor gene, found in all humans. Its protein, also called by the synonym BRCA1, is responsible for repairing DNA.
Mutations in BRCA genes are linked to the early onset of breast and ovarian cancers. But the effect of most mutations is unclear. Now new research can distinguish harmless from dangerous mutations.
Many people associate the word cancer with major illness or death.
Labelling very low-risk conditions as cancers can cause unnecessary anxiety and lead to overtreatment.
New research shows the risk of lung cancer slowly increases five to 10 years after a breast radiation treatment; a form of brachytherapy developed in Canada is the safest treatment to reduce this risk.
New research reveals the risks of lung cancer after breast cancer radiotherapy and identifies the best treatment to reduce these risks.
Breast cancer tumours behave, and are treated, differently.
Headlines that 70% of women with breast cancer don't need chemo need to be heeded with caution: it's a very specific (but substantial) subtype that was studied.
We only know if a cancer has been cured in hindsight.

A cancer is in remission when it can no longer be detected. But we only say it's cured when it hasn't come back for a certain time – and that differs for different cancers.
Unfortunately, there is no net benefit-ometer for breast cancer screening.
Exposure to omega-3 fatty acids during a child’s early years may play a role in reducing breast cancer risk later in life.
New research suggests omega-3s from seafood to be more effective at reducing breast cancer risk than those from plant-based sources.
Most doctors and nurses agree exercise is beneficial but don’t routinely prescribe exercise as part of their patients’ cancer treatment plan.

Historically the advice to cancer patients was to rest and avoid activity. We now know this advice may be harmful to patients, and that every person with cancer would benefit from exercise medicine.
Genetic testing for breast cancer gene mutations is now available. But it could lead to over treatment.
A genetics testing company recently won approval from the FDA to market a test that can identify a breast cancer gene mutation. But what are women supposed to do with that information? There's risk involved.
Many people aren’t aware of the long-term risks alcohol poses to health.
The growing list of alcohol-related diseases includes bowel cancers, mouth and oesophageal cancers, breast cancers, heart disease, respiratory infections and mental health problems.

Research has resulted in advances in treating breast cancer in recent decades, but a wide gap exists in mortality rates between African-American women and white women. Here's a look into why.
The researchers looked at cancer occurrence in those exposed to higher intakes of ultra-processed foods, compared to lower intakes.
The study showed that every 10% increase in consumption of ultra-processed food was linked to a 12% increase in developing some types of cancers. But it didn't show the processed food caused cancers.

Great strides have been made in cancer medicine over decades, but it's important not to forget the growing role that kindness and empathy play in good care.
Liquid biopsy is less invasive than standard biopsy, where a needle is put into a solid tumour to confirm a cancer diagnosis.
There are currently few effective and non-invasive methods to screen for early stages of cancer. But scientists have now developed a new blood test that promises to detect eight different cancers.
Different people have very different chances of being diagnosed with breast cancer.
There is usually no one factor that causes breast cancer. It's likely a combination of the effects of a person's risks combined with an element of bad luck.
Inflammatory breast cancer, a pernicious form of the disease.
Breast cancer awareness month may be over, but don't put away your pink. The disease is with us year-round. While researchers have found several ways to treat it, here are some things to know.

The majority of research suggests the benefits of mammography screening greatly outweigh the harms for women over age 40.
African-American women are about three times more likely to be diagnosed with triple negative breast cancer, an aggressive form of the disease.
Researchers have long been looking for clues into how to treat triple negative breast cancer. Could fighter blood cells that infiltrate the tumor provide insight?
There may be a very good reason for not wanting to get up in the morning when it’s still dark.
Evidence for a link between breast cancer and artificial light appears to be growing. Do studies showing higher risk of breast cancer the farther west a woman lives in a time zone add to the science?
Breast cancer rates in China are rising, and are expected to continue rising for the next three decades.
